Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If users take images or use dedicated mapping software to obtain direction, then direction information can be acquired, but the operation process becomes complicated
Solution Approach 1:
The electronic device automatically determines direction by utilizing sensors already fixed on the user's body (such as accelerometer, gyroscope, magnetometer in smartwatch or smartphone). The system self-calibrates and self-determines orientation without requiring external imaging devices or specialized mapping software, making the device serve its own direction-finding function.
Solution Approach 2:
The patent makes the electronic device multi-functional by enabling it to perform both its primary functions (timekeeping, communication, etc.) and direction determination using the same sensor suite. The sensors originally designed for motion detection and positioning are repurposed to determine directional orientation, eliminating the need for dedicated mapping software or separate imaging devices.
2Measurement precision
If multiple sensors are used to determine posture direction, then measurement accuracy improves, but device complexity increases
Solution Approach 1:
The patent combines multiple sensor types (accelerometer, gyroscope, magnetometer) into a unified direction determination system. These sensors are merged to work together, with their data processed collectively to calculate posture and orientation. This integration leverages the complementary strengths of each sensor to achieve accurate 3D orientation determination without requiring separate dedicated systems.
Solution Approach 2:
The patent introduces an intermediary processing layer that coordinates data from multiple sensors. The processor acts as an intermediary, receiving raw data from various sensors, performing coordinate transformations, and synthesizing the information to determine final posture and direction. This intermediary processing simplifies the complexity by providing a unified computational framework rather than requiring direct integration of all sensor components.

AI summary
An information processing method and an electronic device are provided. The method includes: obtaining first parameter information indicating a current posture of a first body part by a first sensor among M sensors of an electronic device fixed on the first body part; judging whether the first parameter information meets a predetermined condition; determining that the current posture of the first body part is a first posture in a case that the first parameter information meets the predetermined condition; obtaining N second parameters by N sensors other than the first sensor among the M sensors, wherein 1≤N<M; and determining a first posture direction that the first body part in the first posture points towards based on the N second parameters.
